Thermostat location on 1977 mustang 302?
The thermostat on a 1977 Ford Mustang with a 302 engine is located at the bottom of the engine, on the intake manifold. It's usually a fairly easy to access location, but you'll need to get under the car or at least have very good access from the top. You might need to remove some hoses and/or parts to get to it easily.
